Subject: [Caml-list] First Class modules -A bug in 4.00?
Date: Thu, 07 Jun 2012 22:35:14 -0400 [thread overview]
Message-ID: <4FD164E2.4050807@gmail.com> (raw)
Hi, List
I am not sure this is a bug or not?
Below is a contrived example:
------------------
module type S = sig
type t=int
module X : sig type u end
end
let f ( module X : S) (y:X.X.u) =
3
--------------------
Error: This pattern matches values of type X.X.u
but a pattern was expected which matches values of type X.X.u
The type constructor X.X.u would escape its scope
-- Thanks
